A footsore nut dropping from an oak tree? (5)
I believe the answer is:
acorn
This clue might be a double definition.
'a footsore nut' is the first definition.
'acorn' can be an answer for 'nut' (I've seen this in another clue). I am not sure about the 'a footsore' bit.
'dropping from an oak tree?' is the second definition.
I know that 'oak' relates to this answer.
Can you help me to learn more?
(Other definitions for acorn that I've seen before include "Nut of oak tree" , "From which a tall tree may grow" , "from which something bigger may develop" , "From which a "tall oak" may grow" , "Might source" .)
